Interoception refers to the ability to perceive our own internal states. It is crucial for physical integrity and for successful cognitive functioning, as it underpins decision making and emotion regulation. Recent research has shown that social contact allows adults to sharpen their interoception. However, previous studies investigated a strict and standardized type of social contact, far from ecological situation and did not allow to determine if the use of social contact could improve interoception during real interactions. The purpose of the present project is to (I) Determine whether social contact, as performed in everyday life situation, can increase interoception and (II) determine if social contact impacts interoception, or cognitive ability in general.
